Local police are investigating a shooting at Charles Young Park that killed one person and injured four others in Lexington, Kentucky, on Saturday evening.

A 4-year-old, a 14-year-old and two adults were taken to hospital with injuries that were not considered life-threatening, local police chief Lawrence Weathers said. The person who was killed was not immediately identified.

Kentucky Governor Andy Beshear announced the shooting while speaking at a Democratic Party dinner at a downtown hotel. The Lexington Police Department blocked off several roads around the park, while State Police officers were also at the scene, the Lexington Herald-Leader reported.

Authorities had not released information about a suspect or possible motive. Weathers said he did not believe there was an ongoing threat to the public.

The shooting took place during East End Day, a local community event held at the park. Tents remained at the scene as police investigated.

One Lexington Director Devine Carama, who said he was at the event, described the shooting as devastating, local media reported. In a Facebook post, Carama said he had been sheltering four young people when a person nearby was shot.

“Gunfire at a peaceful event, in broad daylight, with women and children present is unacceptable,” Carama said.
